Encoder 2: Rotor Position Adaptation Corrects Deviation; Encoder 2: Battery Voltage Pre-Alarm - Siemens Sinamics S120 Diagnostic Manual

232431 <location>Encoder 2: Deviation, position incremental/absolute too large
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: NONE
Cause: When the zero pulse is passed, a deviation in the incremental position was detected.
For equidistant zero marks, the following applies:
- The first zero mark passed supplies the reference point for all subsequent checks. The other zero marks must have
n times the distance referred to the first zero mark.
For distance-coded zero marks, the following applies:
- the first zero mark pair supplies the reference point for all subsequent checks. The other zero mark pairs must have
the expected distance to the first zero mark pair.
Alarm value (r2124, interpret decimal):
Deviation in quadrants (1 pulse = 4 quadrants).
Remedy: - check that the encoder cables are routed in compliance with EMC.
- check the plug connections
- replace the encoder or encoder cable
- Clean coding disk or remove strong magnetic fields.
232432 <location>Encoder 2: Rotor position adaptation corrects deviation
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: NONE
Cause: For track A/B, pulses have been lost or too many have been counted. These pulses are presently being corrected.
Alarm value (r2124, interpret decimal):
Last measured deviation of zero mark in increments (4 increments = 1 encoder pulse). The sign designates the direc-
tion of motion when detecting the zero mark distance.
Remedy: - check that the encoder cables are routed in compliance with EMC.
- check the plug connections
- replace the encoder or encoder cable
- check encoder limit frequency.
- adapt the parameter for the distance between zero marks (p0424, p0425).
232442 <location>Encoder 2: Battery voltage pre-alarm
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: NONE
Cause: See also: p0491 (Motor encoder fault response ENCODER)
Remedy: - replace battery.
